Ahakoa e tohu ana ngā lumens i te kanapa whānui, ka ine te tawhiti o te hihi i te whai huatanga o te haere me te whakamārama a te mārama i ngā mea tawhiti. Tērā pea he kanapa te āhua o te rama matua he 300 lumens engari kāore e whai hua mō te tawhiti mena ka tukuna noa te mārama ki te huarahi poto. Ko te Candela, he ine mō te kaha o te mārama, e whakaatu ana i te kukū o te hihi. He hononga te kanapa me te tawhiti o te hihi engari kāore i te ōrite tika. Ka whakamārama te rama waipuke lumen-nui i tētahi wāhi tata nui engari kāore e whiti ki tawhiti. I tetahi atu taha, ka taea e te rama rama iti-lumen me te hihi arotahi te whakatutuki i ngā tawhiti roa ake. He mea nui te hoahoa hihi me te whai huatanga o te arotahi ki te tatau lumen mata hei whakatau i te tawhiti o te hihi.

He rerekē ngā tauira hihi o ngā rama matua:

• Ngā kurupae waipukehe whānui, he marara hoki. He pai mō ngā mahi tata engari kāore e uru ki tawhiti.
• Ngā kurupae irahe arotahi. Ka tae atu ki ngā tawhiti tawhiti, he mea pai mō te kite i ngā tūponotanga, i ngā mea tawhiti rānei. He maha ngā rama matua kounga teitei e tuku ana i ngā hihi waipuke me ngā hihi ira, e whakarato ana i ngā whakamahinga maha. Ko te hoahoa whatu, tae atu ki te āhua whakaata me te arotahi arotahi, koia te mea matua e whakatau ana i te tawhiti hihi, ehara i te lumens anake.

Ngā Momo Pūhiko me te Whakamārama mō te Ora

E rua ngā momo pākahiko e whakamahia ana e ngā rama matua: he pākahiko ka taea te whakahou me te pākahiko ka taea te whakakore. He rerekē ngā painga me ngā ngoikoretanga o ia pākahiko. He nui ake te kaha o ngā pākahiko ka taea te whakahou, pērā i te lithium-ion. He pai mō ngā taputapu he nui te mimiti, ā, ka mau tonu te rere o te hiko nā te iti o te ātete o roto. Ahakoa he nui ake te utu tīmatanga, he iti ake te utu mō ngā pākahiko ka taea te whakahou i te wā roa mā te karo i ngā utu whakakapinga maha. He kōwhiringa pai ake hoki mō te taiao nā te roa o te ora me te iti ake o te maka atu i ngā pākahiko kotahi te whakamahinga. Heoi, me whakamahi hiko ngā rama matua ka taea te whakahou hei utu, ka raru pea tēnei i te wā e motu ana te hiko, i ngā wāhi tawhiti rānei kāore he pūtake hiko o waho.

Ko ngā pākahiko whakakorekore, arā, ko ngā pūtau kawakore AA, AAA rānei te nuinga, he māmā noa iho, ā, he whānui hoki te wātea. Kāore e hiahiatia he hanganga utu. Heoi, ka mimiti, ka turuturu rānei ina kore e whakamahia, ka kino pea te taputapu.

Ko te roa o te mahi a te pākahiko, te roa rānei o te mahi, e tohu ana i te roa o te mahi a te rama matua i runga i te utunga kotahi, i te huinga pākahiko rānei. Ko te tikanga, ka whakaratohia e ngā kaihanga ngā whakaritenga mō te roa o te mahi mō ngā tautuhinga kanapa rerekē.

Ngā Whakaaro Taumaha me te Whakamarie

He nui te pānga o te taumaha o te rama matua ki te whakamarie, inā koa i te whakamahinga roa. Ka whakaitihia e te rama matua māmā te taumaha o te kaki, ā, ka whakaitihia te pekepeke i ngā mahi hihiri pēnei i te oma ara. He maha ngā wā ka kitea e ngā kaiwhakamahi he pai ngā rama matua tata ki te 80 karamu mō te mau roa. Hei tauira, i kōrero tētahi kaiwhakamahi he pai ki a rātou te Zebralight H600, tata ki te 111-112 karamu te taumaha, mō te hikoi me te kore he whitiki o runga. I kī tētahi atu kaiwhakamahi me te Nitecore HC90 (135g rama + 46g pākahiko = 181g katoa) "kua wareware ahau kei a au," he tohu tino whakamarie ahakoa te taumaha teitei. Mō ngā mahi pēnei i te hopu manu, ko te nuinga o ngā rama matua mai i te 8 auneke (tata ki te 227g) ki te 16 auneke (tata ki te 454g). Ko te Superior Hellcat Coon Light, he 8 auneke, e kiia ana he pai mō te whakamahinga roa nā tōna hoahoa mama.

He mea nui anō hoki te hoahoa o te whitiki hei āwhina i te whakamarie me te pumau. He rerekē ngā taumata tautoko me te tohatoha taumaha o ngā momo whitiki.

Mā te whitiki rapa kotahi ka whakamarie te tinana, ā, ka ārai i te paheke. Heoi, mō ngā rama upoko taumaha, ngā mahi taumaha rānei, ka nui ake te whakamarie me te pumau o te whitiki o runga mā te tohatoha i te taumaha puta noa i te upoko. Ko ētahi kaiwhakamahi e pai ake ana ki te mau i te rama upoko i runga i te potae, i te pōtae rānei, ka nui ake te whakamarie me te pumau mā te whakauru i te rama upoko. Mā ngā whitiki whakarerekē ka noho pai te tinana, ka ārai i te nekeneke, i te pekepeke rānei o te rama upoko i te wā e neke ana. Mā te whakakī i te pūwāhi pa o te rae ka whai wāhi atu ki te whakamarie whānui i te wā roa e mau ana.

Ngā Whakatauranga Ātete Wai me te Puehu (IPX)

Me tu atu ngā rama o waho ki ngā āhuatanga taiao rerekē. He mea nui te ātete ki te wai me te puehu mō te mahi pono. Ka whakarōpūhia e te waehere Ingress Protection (IP) te ātete o tētahi taonga ki te wai me te puehu. Ko te whakatauranga IPX e tohu ana i te ātete wai. Ko te 'X' i roto i te whakatauranga IPX e tohu ana kāore he whakamātautau whaimana mō te ātete puehu. Ehara i te mea kāore he parenga puehu o tētahi taputapu, engari kāore ngā kaihanga i whakahaere i ngā whakamātautau ine i taua wāhi. Ko te tau i muri i te 'IPX' e pā ana ki te taumata o te parenga ki ngā wai, te nuinga o te wai.

Mā te pūnaha whakatauranga IPX ka mārama te roa o te mau o te rama matua ki te makuku. He rerekē ngā taumata tiaki o ngā whakatauranga rerekē:

Mō te nuinga o ngā mahi o waho, he pai te tiaki i te ua me ngā taupatupatu e te whakatauranga IPX4. Ko ngā mahi e uru ana ki te ruku wai, pērā i te hoe waka, te ruku ana rānei, me teitei ake ngā whakatauranga pērā i te IPX7, IPX8 rānei. Mā te mārama ki ēnei whakatauranga ka āwhina i ngā kaiwhakamahi ki te whiriwhiri i te rama matua e tika ana mō ā rātou mahi mōrearea me ngā wero taiao.

Ngā Aratau me ngā Āhuatanga Mārama Matua

He maha ngā momo rama o waho o ēnei rāngā aratau rama me ngā āhuatangaKa whakarei ake ēnei i te whakamahinga, ā, ka urutau hoki ki ngā āhuatanga rerekē. Ka taea e ngā kaiwhakamahi te arotau i ā rātou rama mō ngā mahi, ngā taiao rānei kua whakaritea.

He rerekē ngā tauira hihi o ngā rama matua hei whakatutuki i ngā hiahia rama rerekē. Ko ngā momo matua e rua ko ngā hihi waipuke me ngā hihi ira. He rerekē ngā whakamahinga me ngā painga o ia tauira.

Ka whakaratohia e ngā rama waipuke he taupoki whānui. Ka tohatoha ōrite te māramatanga ki runga i tētahi wāhi nui. Ka whakatauira tēnei i ngā āhuatanga o te awatea noa i te tawhiti tata. Ka taea e ngā kaiwhakamahi te whakamahi pai i ō rātou tirohanga taha. He pai ngā rama waipuke mō ngā mahi tawhiti tata e hiahia ana kia taupokina whānuitia, pērā i te whakatū puni, te whakatere rānei i ngā ara whānui. He maha ngā wā e hiahiatia ana he iti ake ngā lumens nā te mea ka horapa te kaha. Ka roa ake pea te wā oma nā te iti o te kaha i ngā tawhiti poto.

He kuiti, he kaha hoki te hihi o ngā rama rama. Ka whakamārama i ngā wāhi tawhiti. Nā tēnei ka pai mō ngā āhuatanga e hiahia ana kia kitea whānuitia. Ka taea e ngā kaiwhakamahi te matawai i ngā wāhi tawhiti mō ngā tūponotanga, ngā tohu ara rānei. Ko te tikanga, me nui ake te maha o ngā lumen o ngā rama rama hei whakaata pai i te māramatanga mō ngā tawhiti roa. He nui ake te kaha e whakamahia ana e rātou, ā, he poto ake te wā e oma ai i ngā rama waipuke.

He maha ngā rama matua e tuku ana i ngā tautuhinga hihi-rua, hihi-maha rānei. Ka whakakotahihia e ēnei te roa o te whiti o te rama me te whānui o te uhi o te rama waipuke. Ka whai hua tēnei whānuitanga o ngā mahi pēnei i te oma ara, te hikoi tere rānei. Ka taea e ngā kaiwhakamahi te tautuhi i ngā tohu ara tawhiti me ngā mea tata me te kore e huri i ngā aratau.
